EDMUND D. GILBERT, DEcEAsED, BY CLARA A. GILBERT AND JOSEPH DONALD DGEQ EXECUIOBS, rHILADELrnIA, PENNSYLVANIA,

BLOW-TORCH.

Pennsylvania, are the executors of the last will and testament of E MUND D. GILBERT, deceased, and that the sald ,EDMUND GILBERT invented certain new and useful Improvements in Blow-Torches, of whichplates 17 and 18, by which the rods may be the following is a specification.

Th1s invention relates .to improvements 7 in blow torches and particularly relatesto blow torches in which air and gas are used for heating purposes.

The object of the invention is to produce 1 a blow torch which issimple in construction and which can be manufactured at a low cost; a further object of the invention is to provide means for independently regulating the flow of air and gas through the torch; and a further object of the invention is to provide valves in the torch which will re-, main in a fixed position and which may be readily adjusted by the fingers of the hand in which the torch is held, as will be hereinafter more fully described and claimed. Referring to the drawings; Figure 1 is a perspective view of the improved blow torch; Fig. 2 is a vertical longitudinal sectional View of the blow torch; and Fig. 3 is a transverse section on line 33 Fig. 2.

In the drawings in which like reference characters refer to like parts 1, represents the body portion made of a solid piece ofmetal, of suitable length to form a handle. The body portion is preferably made elliptical in cross-section, with longitudinal grooves formed along the edges thereof to receive the inlet pipes 2 and 3, which are secured in said grooves formed in the body portion. Thus is formed a rounding and convenient place for gripping the torch in the hand.

A central chamber 5 is formed in one end of the body portion, into which is fitted and secured the outlet pipe 6. A smaller outlet pipe 7 is located inside of the pipe 6 and said smaller pipe extends farther into the body portion and is secured in the mouth of the chamber 8 formed in the body portion. An aperture 9 formed in the inlet pipe 2 registers with an aperture 10 in the body portion; a passageway is thus formed between the inlet pipe 2 and the outlet pipe Specification of Letters Patent.

' 7. A similar aperture 12 is formed in the 1nlet pipe 3 and connects with a passageway through the body portion leading into the chamber 5 and to the outlet pipe 6.

Rods 1a and-15 forming valves are fitted intothe open ends of the inlet pipes-2 and 3. Said rods are provided for opening and closing the apertures 9 and 12 formed in the 1nlet pipes 2 and 3. Secured to each of the valve rods 14L and 15, are finger grip moved in and out by the fingers of the hand holding the. torchand thus control the flow" of airand gas.

The finger grip plates 17 and 18 are; made with concaved edges and'projecting corners for better fitting the fingers. The concaved edges of the plates 17 and 18, adjacent to the outlet pipe 6, fit around said pipe and are guided by the pipe; this holds the rods 14 and 15 rigid and prevents the said plates from turning.

VA sleeve 20, is slidably mounted uponthe outlet pipe 6 and may be secured by the setscrew 21 in a position to limit the outward Patented Sept. 3, 1918. Application filed January 20, 1917. Serial No. 143,433. i

movement of the finger grip plates 17 and v 18. When the valve rods 14 and 15 have been adjusted to the desired position the sleeve 20 may be moved along the outlet pipe 6. until it strikes one ofthe finger platesand when the sleeve is secured in this position it will act as a guide for resetting the valve rods in the same position after they have been moved inwardly to close off the flow of air and gas, and it is desired to again open the valves to the same adjustment.

The ends of the inlet pipes 2 and 3, which receive the valve rods, project beyond the body portion and the free ends of the pipes are provided with longitudinal slots 22 which permit the metal forming the ends of the pipes to be contracted and tightly im pinge against the valve rods to prevent the pressure of the medium in the inlet pipes from moving the valve rods.

Flexible connections 23 and 24: are attached to the inlet pipes 2 and 3 and supply air and gas to the torch. The pipe 21s preferably used for theair supply and the pipe 3 for the gas supply.

Having thus described the invention we claim and desire to secure by Letters Patant:-

comprising, a body portion, inlet pipes se-mounted-in the inlet pipes, finger grip mem cured to the body portion, said inlet pipes extending throughput the length of the body portion to form a hand grip, an outlet pipe secured in the body portion and said body portion having passageways formed therein leading from the inlet pipes to the outlet plpe.

2. In a torch the combination, of a body site sides thereoi? in which grooves said inlet pipes are secured to complete the elliptical formation of the hand grip, an outlet pipe secured in thebody portion and said body portion having passageways formed through the same.

4:. In a torch the combination, of a body portion, inlet pipes secured to opposite sides of the body portion, an outlet pipe secured in the body portion and located centrally between the inlet pipes, rods slidably mounted in the inlet pipes, finger grip plates upon the ends of the said rods, said finger grip plates. having portions thereof embracing the said out-let pipe and guided by the latter.

5. In a torch the combination, of a body portion, inlet pipes secured to opposite sides of the body portion, an outlet pipe secured in the body portion located centrally between the inlet pipes, valve rods slidably bers on the valve rods, and a stop adjustably secured upon the outlet pi'pe for engaging the finger grip plates on the valve rods.

6.111 a torch, the combination, of a body portion, inlet pipes secured to opposite sides of the body portion, tl1e ends of the said inlet pipes projecting beyond the end of the body portion, valve rods slidably mounted in the inlet pipes, said projecting ends of the inlet pipes having longitudinal slots formed therein to permit the ends of the pipes to be contracted and impinge against the valve rods, outlet pipes secured in the body portion, and passageways formed in the body portion connecting the inlet pipes with the outlet pipes.

7. In a torch the combination, ofa body portion, inlet pipes secured to the body portion, chambers formed in thebody portion communicating with the inlet pipes, outlet pipes secured in the body portion and communicating with the chambers in the body portion, valve rods slidably mounted in the inlet pipes, finger grip plates upon the valve rods, said finger grip plates having conc'aved sides to embrace the outlet pipe located'be-- tween them, a sleeve adj ustably secured upon the outlet pipe forming a stop, and contracted ends upon the inlet pipes to impinge against the valve rods.

In testimony whereof We afiix our signatures in presence of two witnesses.
